--description--

145 is a curious number, as 1! + 4! + 5! = 1 + 24 + 120 = 145.

Find the numbers and the sum of the numbers which are equal to the sum of the factorial of their digits.

Note: as 1! = 1 and 2! = 2 are not sums they are not included.

--hints--

digitFactorial() should return an object.

assert.typeOf(digitFactorial(), 'object');

digitFactorial() should return { sum: 40730, numbers: [145, 40585] }.

assert.deepEqual(digitFactorial(), { sum: 40730, numbers: [145, 40585] });

--seed--

--seed-contents--

function digitFactorial() {

  var sum = 0;
  var numbers = [];
  return { sum, numbers };
}

digitFactorial();
